GAS-LINE LOCK FOR AUTOMOBILES.

Specification of Letters Patent.

Application filed December 8, 1919. Serial No. 343,153.

MARLEY, re-

provided with means whereby it may be locked in closed position wherebyto prevent theft of an automobile.

An important and more specific object 18 the provision of a device ofthis character in'which the valve is of the gate type and screw operatedwhereby it may be moved to open or closed position, the actuating memherbeing operable by means of a key.

Another object is the provision of a device of this character whichwillbe simple and inexpensive in manufacture and installation, which maybe applied at any desired point between the gas tank. and carbureter,

which will be efficient and positive in action, durable in service, anda generalimprovement in the art.

With the above and other objects andadvantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed-and claimed, and illustrated in the accompanying drawing inwhich v a Figure ljis a longitudinal sectional view through part of mydevice,

Fig. 2 is a longitudinal, sectional view taken on a plane parallel toFig. 1, and

Fig. 3 is a longitudinal sectional view on a lane at right angles tothat of Flg. 1.

eferring more particularly to the draw:

ing, the letter A designates a portion of the I gas line leading fromthe supply tank to carbureter, not shown, of an automo- 1 e. v v

In carrying out my invention I provide a valve casing 10 which isinterposed and suitably connected within the gas line A and which isrovided centrally with a valve seat 11.

1 1, is a gate member 12 formed as a disk which is mounted for slidablemovement in the county of' ovable within the casing; 10 and adapted toengage and close the seat any suitable manner, as by means of screwthreads, with the valve casing 10 is a guide .member 15 through whichthe stem 14 operates and upon the upper end of which is secured, as bythreading, the cylinder barrel 6 of a lock structure. Rotatable withinthe barrel 16 is the lock cylinder 17 having the usual key slot 18. Thislockemechanism is ofcourse provided with the usual wards. The upper endof the stem 14 extends into the cylinder 17 and is formed for engagementby a suitable key 19 insertible within the slot 18 and adapted to rotatethe cylinder 17. v I I The device being in position, in order to closeand lock the gas line, it is merely necessary that the operator insertthe key 19 within the slot 18 and give it several complete rotations inthe proper direction, whereupon the consequent rotation of the stem 14will cause movement of the gate valve 12 into engagement with its seat,cuttingofi communication with the pipe line A. It is of course obviousthat when the valve is closed the automobile thus equipped cannot bestolen as there is no means for supplying gasolene, or whateverother-fuel is used, to the carbureter. When it is desired to reestablishcommunication it is merely necessary, that the operator reinsert the keyand rotate the cylinder in the op-- posite direction whereupon the valve12' will be disengaged from its seat.

In order to provide protection for the device I make use of a hood 20formed as a shell threaded or otherwise secured upon the valve casing 10and inclosing the upper portion thereof, the member 15 and the cylinderbarrel 16.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claim.

Having thus described my invention, I claim A device of the characterdescribed comprising a valve casing interpos'edin the gas line pipe ofan automobile and provided with a valve seat, a valve slidablewithin'said casing and adapted to close said seat,

rotatably disposed within said guide member and threaded at one end forengagement Within the threaded opening in said valve member, a lockstructure including a cylinder barrel casing mounted upon said guidemember and having a disk-like head, a cylinder barrel rotatable Withinsaid barrel casing and provided with a key receiving slot, the other endof said stem extending into said cylinder barrel, a key insertible insaid slot to rotate said barrel and thereby to effect rotation of thestem to seat or unseat said valve, and an enlarged portion formed onsaid casing, and a shell threaded onto said enlarged portion and engaing said head.

11 testlmony whereof I afiix m signature.
